NTD3535I16 是国星光电基于 SMD3535-3P 封装的近红外(NIR)发光二极管,工作波长覆盖 925nm~955nm,典型应用为夜视照明、红外通信、接近/距离传感及生物识别补光等场景。该器件在宽视角(120°)下提供较高辐射强度(65 mW/sr),适合需要大范围均匀照明或漫射光源的系统设计。
备注:给出的 350 mA 与 110 mW 耗散之间存在表面上的矛盾:若按 Vf = 1.42.0 V 与 350 mA 连续工作,则器件功耗约 0.490.70 W,远超 Pd=110 mW。因此 350 mA 更可能为短脉冲或绝对最大值,设计中必须以 Pd 与热阻为依据进行连续电流限制,或向供应商确认脉冲额定条件。
总结:NTD3535I16 提供在 925–955 nm 范围内较宽谱的近红外辐射与 120° 大视角,适合漫射式近红外照明场景。但设计时必须重视热管理与驱动策略,严格按照 Pd 与数据表脉冲/连续额定来确定工作点,以保证性能与寿命。若需详细电气/热仿真数据或封装尺寸与回流曲线,建议结合厂方完整数据手册做最终设计。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
